Fantasy Tip: Siemian was never able to find his groove in 2017. When he was healthy he was prone to turn the ball over much too often. Perhaps a team like the Arizona Cardinals would be willing to part with a late-round pick since Denver's former offensive coordinator, Mike McCoy, now serves in the same role in Arizona. Nonetheless, Siemian is not a starting fantasy quarterback.

Fantasy Tip: Cousins has been on the fringe of an elite fantasy quarterback the last couple of years without a lot around him. If he went to Denver to throw to established receivers, he could firmly entrench himself in the top-five at the position.

Denver Broncos DE Derek Wolfe (neck) had surgery this offseason to alleviate nerve pain in his neck. The procedure enlarges the passageway where the spinal nerve exits the spinal canal. Wolfe, who also underwent stem-cell treatments, said he had dealt with neck pain since 2013.

Denver Broncos WRs Demaryius Thomas and Emmanuel Sanders could both stay on the roster in an effort to better lure a big-name quarterback, according to NFL Network's Ian Rapoport. Sanders, in particular, had been rumored to be traded or released this offseason.

Fantasy Tip: The Broncos need more money to make a good pitch to someone like Kirk Cousins. If they keep Thomas and Sanders then they'll likely released Aqib Talib and C.J. Anderson. If they do land a top quarterback then the fantasy value of both Thomas and Sanders will naturally increase.

Denver Broncos WR Emmanuel Sanders could be placed on the trade block this offseason because of his salary and his uncertain durability, in the opinion of The Denver Post's Nicki Jhabvala. Sanders missed four games this season because of an ankle injury and is scheduled to have salary cap hits of around $10.9 million and $12.9 million over the next two seasons.

Fantasy Tip: Sanders had a disappointing 2017 season with only 555 yards and two touchdowns. He has been a solid receiver since entering the league but may be on the move during the offseason. He can be a starter for most teams in the NFL and could be a No. 3 fantasy receiver depending on his team.

Denver Broncos WR Demaryius Thomas has a $1 million option in his contract that would trigger the final two years of the contract if exercised, and the Broncos have until the middle of March to make a decision on the option. The team would take on $3.1 million in dead money if they decide to decline the option. Thomas would count around $12 million and $17.5 million in the cap space over the next two seasons if the option is picked up.

Fantasy Tip: Thomas saw a small drop in his stats this season but still finished with 83 receptions, 949 yards and five touchdowns. Thomas should be a starting receiver for a team in 2018 and can be a No. 2 fantasy receiver.
